Echinacea plant named ‘Hot Lava’

ABSTRACT

A new and distinct  Echinacea  plant named ‘Hot Lava’ characterized by large, orange red inflorescences with prominent dark cones, well-branched upright flower stalks, and excellent vigor.

Botanical denomination: Echinacea hybrid.

Variety designation: ‘Hot Lava’.

The present invention relates to a new and distinct cultivar ofEchinacea and given the cultivar name ‘Hot Lava’. Echinacea is in thefamily Asteraceae. This new cultivar originated as a fourth generationseedling from a planned breeding program using the parents Echinaceaparadoxa and Echinacea purpurea ‘Ruby Giant’ (unpatented) for theinitial cross. The exact parents of this selection are unknown, unnamedproprietary, unreleased plants.

This new Echinacea cultivar is distinguished by:

-   -   1. Large, orange red inflorescences with prominent dark cones    -   2. Well-branched upright flower stalks    -   3. Excellent vigor

This new cultivar has been reproduced only by asexual propagation(division and tissue culture). Each of the progeny exhibits identicalcharacteristics to the original plant. Asexual propagation by divisionand tissue culture using standard micropropagation techniques withterminal and lateral shoots, as done in Canby, Oreg., shows that theforegoing characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations. The presentinvention has not been evaluated under all possible environmentalconditions. The phenotype may vary with variations in environmentwithout a change in the genotype of the plant.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new Echinacea cultivarbased on observations of 18-month old specimens growing in the ground inthe field in full sun in the trial bed under typical outdoor conditionsin Canby, Oreg. The plants had been moved from one trial field toanother the fall before. Canby is in Zone 8 on the USDA Hardiness mapTemperatures range from a high of 95 degrees F. in August to an averageof 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches peryear in the trial fields in Canby, Oreg. The color descriptions are allbased on The Royal Horticultural Society Colour Chart, fifth edition.

COMPARISONS TO SIMILAR ECHINACEA

Compared to Echinacea ‘Tiki Torch’ (U.S. Plant Pat. No. 18,839), the newcultivar has a flower that is redder.

Compared to Echinacea ‘Tomato Soup’ (U.S. Plant Pat. No. 19,427), thenew cultivar has more orange in the flower and fades to a bicolor ratherthan being red and fading to a dull red.

Compared to Echinacea ‘Sunset’ (U.S. Plant Pat. No. 16,424), the newvariety has larger flowers with deeper orange red color.
